The Big Harris bench is made up of two or three 7mm thick steel sheet supports, hot dip galvanised with a predrilled base plate for ground fixing with bolts (not supplied). The bench is made up of five 138x38mm section timber slats, with a double-sided outer strip in the chosen timber which is fixed to the supports with countersunk screws and reinforced with pre-zinced steel brackets. All timber parts are double coated: the first coat is a base insulating spray and the second finishing coat is a water-based varnish for outdoor use. All steel components are polyester powder coated. Big Harris Bench is also available with corten steel legs.
